My last fridge was deemed to be a sealed system problem, so I purchased a used one to replace it. BAD idea. It worked great to begin with, but noticed there seemed to be more condensation (everything looked fogged up) inside the fridge most of the time.

The freezer also seemed to be a little extra frosty, but was hoping that was just how this fridge worked. Well after about 4 weeks, the fridge would almost constantly run, the fridge was starting to freeze water, the freezer was staying between 0 and 10 and then the motor? fan? started to make a ticking noise, that was constantly getting louder, which was similar to the sound my previous fridge was making and it turned out to be a the fan hitting frost buildup.

So I decided to defrost it and hope that fixed it. And it did, for a couple weeks. There didn't appear to be any frost in the way of the fan, it moved easily, however after I turned the fridge back on, the noise was almost gone. But now the same thing is happening again. Any idea what might be wrong and it if it could be fixed?

Attached pictures are after only about 5 weeks of the fridge running.

Hi, It sounds like you have a part that's bad which controls your defrost cycle. I would start by turning your defrost timer clockwise with a flathead screwdriver, turn it slowly till your refrigerator shuts off, then it will be in the defrost cycle, give it about 5 minutes to see if your defrost heater comes on, the defrost heater is located under your evaporator coil in your 2nd photo above. Feel for heat there after 5 minutes.

Your defrost timer is #4 here:

There is a hole just under your console#12 that you can put your flathead screwdriver in to turn the defrost timer clockwise slowly, without having to remove the console itself.

Here is the defrost timer for your model:
W10822278 Defrost Timer

Had to turn it quite a bit, but it turned off, and there was heat after a few minutes. I can hear dripping water now.

Ok, that indicates your defrost thermostat and defrost heater are working fine. So that just leaves the defrost timer as the culprit, you can order it from post #2.

That is great news! Thank you so much! Is that something I can replace on my own without any special tools?
